The quake's epicenter was about 150 miles from Anchorage to the west of Cook Inlet, near the Chigmit Mountains. The area is southwest of Redoubt Volcano. It was recorded some 70 miles below the earth's surface.

The quake hit about 6:35 p.m. Tuesday and was felt all the way to Fairbanks, according to the Alaska Earthquake Center.

Linda Hull of Clam Gulch, about 65 miles away from the earthquake's epicenter, told the Alaska Dispatch New that she heard a very low rumble before a slow rolling motion started. It was several seconds before she felt a jolt, she said.

"Pictures didn't fall off the walls, but they are all crooked," she said after the quake. Glass figurines fell off her shelves, but didn't break. "Light fixtures were still swaying for about three minutes after the shock hit," she said.
